Nuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu !!!
Well done, that must have been hard. But is that a rickroll homework you are gonna give you up to your teacher ? or did you just do that to rickroll us ? 
or did you find that on the internet ?
I found it on gizmodo,
but, as you asked:
I do have many interesting homework to do, but, almost all of them must be done in portuguese.
And the format isn't the same, so it would be almost impossible for me to rickroll them ...
//Though it is kind a possible to do a rickroll translated
PS: if you want to understand anything go for Google Translator or something like it.
